You missed a few alternatives. I've added them myself, and ran the benchmark again.

I must say that they perform rather poorly.

Benchmark::cmpthese(0, { split => sub { @data = split(/\s+/, $line) }, fixed_length => sub { @data = $line =~ /^.{8} {6}(.{10})(.{10})(.{1 +0})(.{10})(.{10})(.{10})(.{10})(.{10})(.{10})(.{10})(.{10})(.{10})$/ +}, var_length => sub { @data = $line =~ /^.{8}\s+(\S+)\s+(\S+)\s+(\S ++)\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+ +(\S+)$/ }, g => sub { @data = $line =~ /\S+/g; }, unpack => sub { @data = unpack 'A8x6A10A10A10A10A10A10A10A10A +10A10A10A10', $line } });

Result:

Rate g unpack split var_length fi +xed_length g 16954/s -- -54% -70% -76% + -96% unpack 36961/s 118% -- -35% -47% + -91% split 56965/s 236% 54% -- -19% + -86% var_length 70373/s 315% 90% 24% -- + -83% fixed_length 408377/s 2309% 1005% 617% 480% + --

You ignore the first field, I include it... but that shouldn't matter much.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
